Global was contracted by Terra Contracting Services, LLC to serve as Water Treatment Specialists in response to the 2010 Enbridge Oil Spill along the Kalamazoo River. An energy pipeline rupture caused 877,000 gallons of heavy crude oil to spill into Talmadge Creek in Calhoun County, Michigan, which flows into the Kalamazoo River. Global engineered a processing plant for material and slurry dredged from the region upstream of the Ceresco Dam.
Material and slurry were pumped from the 4 dredges to the 14 acre...

77 km Long 3D Canal Floor Sediment/Rock Study for Dredging EstimatesBoat towed streaming dipole-dipole resistivity data were successfully used to estimate geotechnical properties of the canal floor in order to reduce dredging costs for an ongoing Panama Canal expansion program.Site: The 77-km long Panama Canal with 773 line-km of resistivity data collected at 25 m transect spacing inside the canal(fresh water) and then out into the Pacific and Caribbean approach areas (salt water).Instrument: SuperStingR8 with...

Ponds and lakes naturally accumulate sludge and nutrients that lead to eutrophication and eventually pond or lake death. Natural succession is driving all lakes and ponds to become meadows and eventually forest.
To slow or reverse this process and maintain a lake or pond beneficial microbes are critical. These beneficial microbes improve water quality by reducing nutrients and sludge through natural processes.
Reduce Bottom Sludge
Reduce Odors
Reduce Suspended Solids
Waste and Sludge Reducer™...

Potential adverse impacts to the aquatic environment should be minimized whenever possible during an environmental dredging project by selecting realistic and technically feasible environmental targets. These targets need to balance short term impacts with the longer term benefit of removing contaminated sediments from the environment. Environmental dredging is part of the planned remediation of Randle Reef (a 60 hectare zone of mostly polycyclic aromatic hydrocarbon (PAH) contaminated sediments) in Hamilton,...

The Grand Calumet River is a tributary located in Northwest Indiana, which flows into Lake Michigan. Years of industrial pollution caused by nearby steel mills, petro-chemical plants and oil refineries have contaminated the river with oil and other pollutants, which threaten human and ecological health in this watershed. The primary contaminants of concern are carcinogenic Polyaromatic Hydrocarbons in the sediment. PAHs are found in oil and include compounds such as anthracene, chrysene, benzo[a]pyrene and many...
